Trail 66 – RAF Chelveston – Part 2 – Operational Beginnings

In Part 1, we saw how RAF Chelveston began its life in 1940 on land straddling the Bedfordshire–Northamptonshire border as part of Britain’s wartime airfield expansion programme. Initially referred to as Shelton during planning, the station opens in 1941 with basic grass runways before gradually developing into a standard three-runway bomber airfield. In time it would pass into American control as USAAF Station 105.

1941 – From Opening to Operational Beginnings:

Chelveston airfield officially opened its doors on August 15th 1941, as RAF Chelveston, and initially fell under the control of Flying Officer J.B. Townsend, 2 Group, RAF Bomber Command. Still in the process of construction, the airfield was parented by RAF Polebrook, a relationship that dissolved upon Chelveston gaining its full self-governing status on 2nd September that same year.

To provide protection from attack, RAF Podington (now the Santa Pod drag strip) was allocated as a satellite station, and a decoy or ‘Q’ site (Q144A) was constructed at Swineshead. In addition to these measures, an airfield defence unit, 2819 Defence Squadron, was established here with twelve Bofor anti-aircraft guns, providing protection from any roaming enemy aircraft.

Immediately on transfer of the airfield to the RAF, permission was granted to extend the three runways, the main from 4,100 ft to 6,000 ft and the second from 3,700 ft to 4,167 ft. The third, would remain at 3,700 ft for the time being. These extensions, along with further general updating, would eventually bring the airfield up to the Class ‘A’ standard format, making it suitable for the allied heavy bomber fleet. However, progress was slow, and this degree of modernisation would not be achieved for another two years or so.

Construction work therefore continued well into 1942. In addition to the runway extensions, the bulk of the ‘frying pan’ style dispersals were also added, and the accommodation area was extended, enabling upward of some 3,000 personnel to be located here. The bomb store was also added at this point, and the technical area was extended to include a wider range of technical buildings and stores.

The RAF’s 2 Group remained in control of Chelveston for only two months, ownership then transferring to 8 Group in October 1941. 8 Group were a former World War 1 group, who would go on to disband and reform again later, as the famous ‘Pathfinders’ under Donald Bennett.

Although 8 Group was a bomber group, Chelveston’s first resident flying unit would not reflect that role. The new runways, not yet fully completed and strengthened, were incapable of bearing the heavy loads imposed by Bomber Command’s aircraft. Instead, The small, light aircraft of the Central Gunnery School (CGS) were brought in as a temporary measure, giving the unit a much-needed operating base. Lacking a permanent home and  sufficient space to operate, the school also maintained a presence at nearby RAF Thurleigh, effectively dividing its activities between the two airfields. The CGS was a long standing organisation, made up of  several components including the Pilot Gunnery Instructor’s Training Wing, and were destined to eventually move to RAF Sutton Bridge in Lincolnshire. The CGS, being a training unit, trained  gunnery instructors for both fighters and bombers.

From British Training to American Arrival: Chelveston in Transition

The CGS remained at Chelveston only briefly, departing in stages during February and March 1942 once the extension and upgrading works had been largely completed. Initially, part of the training wing relocated to RAF Wittering in Cambridgeshire, before re-joining the remainder of the unit at Sutton Bridge in Lincolnshire the following month. Once reunited, the CGS became one of the largest, single training establishments of the war.

The lull at Chelveston between the CGS’s departure and the arrival of its successor proved far from uneventful though. On 8th May 1942, a tragic accident occurred – and one that was witnessed by only a handful of observers. On that day, a visiting Wellington IC (R1412) of No. 21 OTU, RAF Moreton-in-Marsh, landed at Chelveston and promptly began transferring aircrew to another aircraft preparing to depart. One of the passengers – Air Gunner Sgt. Matthew Callaghan (s/n: 1069247), RAFVR – stepped down from the Wellington and headed over towards the waiting aircraft. Distracted momentarily, he misjudged his position and was killed when he ran into a spinning propellor of the Wellington. He was just a week short of his 27th birthday.*2*3

The tragedy didn’t stop progress though, and two days later a small detachment of the Airborne Forces Experimental Establishment (AFEE)*4 arrived at Chelveston. This small unit was present to test airborne equipment and techniques – the methods and apparatus used to transport men and materiel to the battlefield.

Tracing its origins to the Central Landing School at RAF Ringway in June 1940, the AFEE was established in response to Churchill’s directive for a corps of expert parachutists; later expanding its remit to include gliders and, eventually, rotary-wing aircraft.

At Chelveston though, the newly developed AFEE would use Airspeed Horsa gliders along with their tow aircraft, both the Whitley and the Short Stirling, to test safe loading methods for a range of equipment. A specialist unit, they would go on to test both the General Aircraft Hotspur glider and the Hamilcar, adding to those which provided much needed transport to the continent on both D-day and in Operation ‘Market Garden’.

It was during one of these trials, on 3rd June 1942, that the airframe of Hotspur BT500, suffered severe stress resulting in the aircraft breaking up in mid-air near to the small village of Denford in Northamptonshire. Luckily, the two crew, both of whom were Polish, managed to bale out of the glider, one suffering minor injuries as he did so.

Later in that same June, Chelveston received its second airborne group, an arrival that suggested a potential new owner in the months to come. The American unit, the 60th Transport Group (TG), comprised of the 10th, 11th and 12th Transport Squadrons operating a variant of the C-47 Dakota.  They arrived in staggered sections bringing with them ninety-three officers along with 727 other ranks and fifty-two aircraft all under the command of Lieutenant Colonel A. J. Kerwin Malone. *5

This initial American allocation, would indeed lead to a new ownership of RAF Chelveston. But, with no immediate official ceremony, the change was gradual, and ownership wouldn’t be cemented until the end of the year once all the resident British units had departed.

Activated on 1st December 1940, at Olmsted Air Field in Pennsylvania, the 60th Transport Group was one of the oldest transport groups in the United States Army Air Force, and is said  to be the first to deploy overseas to the European theatre of operations*6. Following its initial training period, the unit prepared for overseas service, with the ground echelon crossing to the United Kingdom onboard the Queen Elizabeth, while the air echelon made the longer, northern transatlantic journey via Greenland; arriving in England around 12th June 1942.

On arrival, the men of the 60th were formally briefed on their conduct both on and off the station, and reflecting common fears of attack, were instructed to carry firearms at all times. Supported by a detachment of RAF personnel led by Squadron Leader Clayton, they also received instruction on the operation of British airfields and the complexities of a busy UK airspace.

Initially, the group’s role centred on transporting goods between air depots and operational airfields, but this sedate role was soon changed to training with the US Army’s airborne 2nd Battalion, 503rd Parachute Infantry Regiment. This relationship lead to the battalion’s first parachute jump over England. As their responsibilities grew, the 60th also began training for specialised operations, a shift formally recognised in mid-July 1942 with its redesignation as the 60th Troop Carrier Group.

However, the 60th’s stay at Chelveston would also be short lived; in early August, they departed the airfield stopping off briefly at RAF Aldermaston before transiting to the 12th Air Force and the North Africa campaign. On departure, they took the airborne forces with whom they had been training, with them. Whilst in North Africa, they would take part in many airborne operations including both the invasion of Sicily and the liberation of Greece, remaining in the Mediterranean theatre for the duration of the war.

The departure of the 60 TCG was not as smooth as one would wish for however. The poor British weather hampered the move, causing it to be delayed on several occasions. When it did finally get away, the second section had to make an unscheduled stop at a nearby airfield as it was approached by a lone German Me110 fighter. Intercepted by RAF Spitfires, the roaming 110 was quickly despatched and the TCG were allowed to continue on their way unhampered. *7

After their departure, Chelveston received a series of visits and inspections by senior Allied figures. These visits sparked rumours of an impending change in operations, and began with Group Captain Donald ‘Don’ Bennett, commander of the newly-formed Pathfinder Force within RAF Bomber Command, who was accompanied by Colonel Duncan of the USAAF. A few days later, the airfield was visited by Brigadier General Ira C. Eaker. It was in the aftermath of Eaker’s visit that ownership of Chelveston truly changed, marking the beginning of a new chapter in the airfield’s long and distinguished career.

In the next part of Chelveston’s history, we see the airfield finally step onto the operational stage. With the arrival of the USAAF’s 301st Bombardment Group and the first B-17 Flying Fortresses, the station began launching real combat missions over occupied Europe. What followed were the opening operations, early trials, and first losses that marked Chelveston’s transition from a developing airfield into an active participant in the Allied air offensive.

Brigadier General Frederick W. Castle – Heartbreak on Christmas Eve, 1944

On the morning of December 24th, 1944, Brigadier General  Frederick W. Castle (s/n 0-319375), woke to the greet the day, and like most pilots facing perilous missions, he probably wondered if it would be his last. However, knowing what I know about Castle from my research, he was a calm, confident and highly competent pilot, so most likely he had every reason to believe in the success of his next mission. Sadly though, that was not to be the case. Castle never made it back that night. On Christmas Eve of 1944, this brave pilot lost his 30th and final battle.

Frederick W. Castle was born on October 14th, 1908 at Fort McKinley in Manila, the Philippines. He came from an active military family and was the son of Col. Benjamin Frederick Castle. Following the end of World War 1, he was to settle in the United States in Mountain Lakes, New Jersey.

From a young age, Castle was destined to follow in his fathers footsteps, groomed for a life of military service. He attended Boonton High School and Storm King Military Academy before moving on to the US Military Academy from where he graduated in June 1930.

His first service was with the New Jersey National Guard, where he stayed for two years  transferring to the Air Corps, March Field, California, then onto Kelly Field in Texas. Castle gaining his wings in October 1931.

Serving as a pilot with the 17th Pursuit Squadron for 3 years, he eventually left the forces returning to civilian life but holding a reserve status. With the entry of the United States into the Second World War, Castle would be called upon by his good Friend Ira Eaker, returning to the fold in January 1942, and being promoted within two months to Major. By the following September, Castle had been promoted yet again, he was now a Lieutenant Colonel.

With the forming of the Eighth Air Force in England, headed by General Ira Eaker, Castle was one of seven high-ranking officers selected to fly with him on the dangerous route over the Bay of Biscay, eventually arriving at Hendon wearing their civilian clothes. Joining Eaker on February 20th 1943 in the DC-3 from Lisbon were: Lt Colonel Frank Armstrong Jnr, Major Peter Beasley, Captain Beirne Lay Jnr, Lt. Harris Hull and Lt. William Cowart Jnr.

Castle desired a combat role, and this desire would lead to him taking over the command of the ailing 94th Bomb Group. His methods of command were initially considered weak, but in the face of low morale and apprehension, he personally took the 94th to some of the furthest targets yet, his first being Oschersleben in the heart of Germany; a mission that went on to inspire the film “12 o’clock High“.  Castle went on to fly in many combat missions including numerous high prestige targets, a role that took him on to Brigadier General and command of 4th Combat Wing.

On Christmas Eve 1944, following a week of poor weather, orders came though for a maximum effort mission, involving every available B-17 and B-24 in support of the troops in the Ardennes. Airfields, supply lines and troop movements were to be attacked, and following weeks of poor weather, a break was at last predicted.

As a joint effort, this would be the largest single attack to date involving 500 RAF and Ninth Air force bombers, 800 fighters and just short of 2,050 Eighth Air Force bombers. Such was the demand for aircraft, that even ‘war weary’ examples, were hastily armed and prepared, many unfit for more than assembly or training duties. Truly an armada of incredible proportions.

Taking lead position, Frederick Castle, was in B-17G-VE, ’44-8444′ “Treble Four“, an aircraft that had itself seen battle experience. Assigned to the 836BS, 487BG, and at RAF Lavenham, it was previously damaged in a raid over Darmstadt. The aircraft was  later salvaged in January 1945.

A veteran of 29 missions, Castle was a more than a competent leader. They set off, the weather was as predicted but with a haze that restricted ground level visibility. It was this haze prevented the fighters from leaving causing an all important delay in the escorts. This delay was not considered a major problem at the time however, as the escorts being faster, would soon catchup and overtake the heavily laden bombers. The Luftwaffe, in an unprecedented move, brought forward fighters into the Liege area to meet the oncoming bombers before any escorts could reach them. In the first few minutes of the battle, four of the 487th BG’s aircraft were downed and a further five forced to land in Belgium.

Castle’s lead plane, suffering problems with one of its engines (possibly due to previous battle damage) was attacked by the first wave of fighters, action was taken to leave the flight and join a formation further back. It was then attacked again, the aircraft catching fire, and the navigator being wounded.

Castle took control, and even though still being attacked, refused to jettison the bombs for fear of killing civilians or allied troops below. Further attacks led to both engines on the starboard wing catching fire, which ultimately led to the fuel tank exploding sending the aircraft into an uncontrollable spin.

Through Castle’s actions, seven of the crewmen were able to leave the aircraft, sadly  though not all survived.

Frederick Castle died in the crash, his body is now buried in Henri-Chapelle American Cemetery, Liege, Belgium, Plot D, Row 13, Grave 53.

His citation reads:

“He was air commander and leader of more than 2,000 heavy bombers in a strike against German airfields on 24 December 1944. En route to the target, the failure of 1 engine forced him to relinquish his place at the head of the formation. In order not to endanger friendly troops on the ground below, he refused to jettison his bombs to gain speed maneuverability. His lagging, unescorted aircraft became the target of numerous enemy fighters which ripped the left wing with cannon shells. set the oxygen system afire, and wounded 2 members of the crew. Repeated attacks started fires in 2 engines, leaving the Flying Fortress in imminent danger of exploding. Realizing the hopelessness of the situation, the bail-out order was given. Without regard for his personal safety he gallantly remained alone at the controls to afford all other crewmembers an opportunity to escape. Still another attack exploded gasoline tanks in the right wing, and the bomber plunged earthward. carrying Gen. Castle to his death. His intrepidity and willing sacrifice of his life to save members of the crew were in keeping with the highest traditions of the military service*3.”

For his action, Frederick W. Castle was awarded the Medal of Honour posthumously. In 1946, the Castle Air Force Base, in the heart of California’s San Joaquin Valley, was dedicated in his name, and on June 20th, 1981, the Castle Air Museum was officially opened on the now closed base, for the purpose of preserving the Air Force and Castle heritage. Museum details can be found on their website. His  name is also on a plaque in the Memorial Park, in Mountain Lakes, New Jersey.

The awarding of the Medal of Honour, reflected the determination and personality of one of Eakers “Original Seven”, who chose to leave a safe position for a combat role, taking on the demoralised 94th, and leading them into some of the Second World War’s most ferocious air battles.
